DESCRIPTION
The TPS65040 is an advanced RF power
management chip for cellular phones, providing a
highly optimized solution for UMTS/WCDMA/GSM
power amplifier applications. This solution improves
efficiency by voltage control of the power amplifiers,
saving power to prolong battery life. The TPS65040
features buck boost DC/DC converters suited for
applications requiring up to 550-mA output current
while dynamically adjusting output voltage from 0.8 V
to 4.2 V with a fast settling time, high performance
8-channel LDO regulators, 8bit DAC, 12bit ADC and
clock distribution buffers of 26 MHz VCTCXO. Each
block can be controlled by serial interface and
external pins. The TPS65040 offers material cost
savings and small size, using a compact 5 mm × 5
mm MicroStar Junior™ package.
